1'0 a/ZZ whom t may concern:

. Be it known that I, JOHN E. MINOTT, o Aurora, in the county lof Kane, Vand in the State of Illinois, have invented certain new and useful Improvements in Door-Stops; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figures l and 2 are side elevations of my device, showing, respectively, iheslidin g bolt projected and retracted. Fig. 3 is avertical section on line c oc of Fig. 1; Fig. 4, an edge view of the same Fig. 5, a side elevation with the rotating cap'-plate removed. Figs. G and 7 are detail views o f said plate, and Figs. 8 and 9 are detail views of the sliding bolt.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to provide a simple, strong, and thoroughly-efficient doorstop; and to this end said invention consists in the door-stop constructed substantially as and for the purpose hereinafter specified.

In the carrying of my invention into practice I employ a circular base-plate A, having two perforated ears d and a at diametrically opposite points, through which screws may be passed to secure said plate to the'door. At its edgethe base-plate has a circular flange B. Pivoted concentrically to the base-plate by a stud or rivet O is a circular plate or disk D, that is of the same diameter as and rests against the flange'. Said disk D has on its inner face an eccentric d, that is placed between and engages shoulders e and e on a bolt or bar E. By the rotation ofthe disk D the boltjnay be moved back and forth." Said bolt, which has aiiat body with a circular enlargement or bead e on its outer end, passes through a slot b in the base-flange B. AIt is also guided in its movements in a straight line by said slot and by means of an elongated straight opening or slot e2, that engages the pivot-pin or rivet C. A block of rubber G or other suitable material is secured within acavity inthe outer end of the bolt to insure the required degree of friction upon the floor or other surface and to protect the latter straight line, a rotary part having an eccen-A tric to actuate said bolt, and a stop-lug7 on said part to engage the bolt, substantially as and for the purpose specified.

2. Ina door-stop, the combination of abaseplate having a circular flange, a sliding bolt passing through a slot in the tlange,'a disk pivoted to said plate concentrically therewith and resting against said flange, an eccentric on said disk engaging shoulders on the bolt, the latter having a guide-slot engaged by the disk pivot, and a stop-lug on the disk, adapted to engage the boltT substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this 4th day of December, V1896.
